FLY SGARER.

Application filed February This invention relates to fly scorers and has as one of its objects to provide a scarer that is simple to construct and efficient in operation.

Another object of the invention is to provide a scarer that will frighten a; d dislodge flies from in front of the closure upon opening of the closure. v

A further object of the invention is to provide a scarer that may fit a right and left hand opening door.

With these and other objects in view reference' is now had to the accompanying drawings in which,

Fig. 1 is a. front elevation of a door equipped with the scarer;

2 is a similar view to Fig. 1 showing the door in the partly opened position;

Fig. 3 is a side elevation thereof;

Fig. 4: is a rear view f the door in the closed position;

Fig. 5 is a similar View to Fig. 1 and showing the scarer in the operable position;

Fig. 6 shows a modified form of the device;

7 is a side elevation thereof;

Fig. 8 is an enlarged front View of one part of the scarer;

Fig. 9 is a fragment of the scarcr taken on the line 9-9 of Fig. 8 and shows its reversed position for a left hand door;

Fig. 10 is a front elevation of a part-of the scarer;

Fig. 11 is a plan view of the lever airm;

Fig. 12 shows a fragment of a modified form I of lever arm Fig. 13 shows a side elevation of a connecting piece;

Fig. 14: shows the reversible position of the lever arm, and;

Fig. 15 shows a detail of a roller bearing.

Having reference to the drawings like nu merals refer to like parts throughout the several views, and the numeral 1 refers to a closure consisting in this case of a. screen door having a door frame consisting of a top frame 2, a right hand frame 3 and a left hand frame 4.

Attached to the top frame 2 by hinges 5, and positioned horizontally, is a framework 6 which may consist of horizontally positioned rods 7 attached to arms 8 carried by hinges 5; or of a single bar 9 formed as shown in Figs. 6, 8 and 9. The purpose of the rods is to carry two or more rows of ribbons 10, depending as shown in the fig- 3, 1927. Serial No. 155,741.

ures, which will be agitated as the frame work is outwardly swung in the course of its operation.

A similar fran'iework 11 is attached to the side frame 3 of the closure and is preferably of similar construction to the top framework and is also similarly mounted on the frame to normally rest against the closure when inactive. lhe top and side framework are operably and positively joined together for united action by a link 12 which may oonsist of a rod 13, as shown in Fig. 6; a bar" 1 1, as shown in Figs. 1 and 3; or a loop 15, as shown in Fig. 10.

The link 12 consists of a plain rod having rings formed on its ends to engage like rings in the extended member 16, while the bar 14 has one free end inserted between rollers 17 carried by the extended member 16 to reduce friction, and the loop 15 is provided with a roller 18 and this roller is mounted in the loop 15 and slidably mounted on the extended member 16, which in this case is elongated.

While the rod 13 and the bar 14 are not readily reversible, the loop 15 is reversible and is attached to the side framework by a connecting piece 19 whereby the loop may be reversed when it is desired to attach the framework to the opposite side t of the closure.

Forming a continuation of the arms 8 is a lever arm 20 rigidly secured thereto and po 'sitioned for slidable engagei'nent with the top of the closure 1, and to change from the right to the left hand opening of the closure in addition to the change made in connecting links 12, the lever arm 20 is also made reversible by means of a connecting piece 21.

This lever arm being positioned to operably engage the top edge of the closure 1, it is obviously located on the underside of the top framework, as shown in Figs. 8 and 9, Fig. 8 showing the position of the lever arm for operation of the device with the closure opening to the left, and Fig. 9 showing the lever arm in a similar position beneath the top framework for opening the closure to the right.

The two positions are also shown in Fig.

14, where the solid line 20 shows the lever arm on one side of the framework and the dotted line 20 shows the reversed position of the lever arm with the position of the frame work unchanged.

By this it will be noted that the device may be adapted to all closures regardless of their direction of opening and that the extending swinging movement of the device is positive with the opening of the closure.

To prevent undue wear and to reduce friction to a minimum a roller 22 may be attached to the top of the closure to contact said lever arm.

here it is desirable to prm'idc greater agitation to the ribbons 10 the lever arm :20 may be sinuously formed as shown in Fig. 12, in which case the arm and with it the framework will be provided with an oseil latinp swinging movement in a vertical plane that will give greater agitation to the ribbons.

The side framework it may be extended downward to a point above the knob 93, to provide for free access to that member, or it may be extended lower down over the closure as shown in Fig. l, in which event an offset Q-tl will be provided for the purpose.

In use the device is attached to the door frame as shown and described when the top framework will normally rest over the up per end of the closure while the side framework will normally rest in close proximity with the opening; side of the closure.

Now it is obvious that a very slight move ment of the closure in the direction of opening will operate the lever arm rapidly at the beginning of the movement owing to the short distance between the pointof contact between the top of the closure and the lever arm. and the pointof hinge of that arm, thus the rapid movement of the top and side framework will scare the flies that naturally gather at the upper end of a closure and at the same time will move outwardly to extend the framework clear of the path of the closure.

Conversely when the closure is returned to its original closed position the framework will remain out ofthe path of the closure and finally swing back to drop to place when that member is closed.

Having thus described my invention, I claim-- 1. In a fly scarer, a swinging horizontally positioned fran'iework hingedly attached to the top frame of a closure, a swinging rertically positioned framework hingedly at tached to the side frame thereof, a reversible link opcrably and positively connecting said frameworks for united actioin and a reversible lei'er arm rigidly attached to and operable in a vertical plane withsaid framework, and positioned to slidably contact said closure to outwardly extend said framework upon opening the closure.

2. in a fly scarer, ahorizontally positioned swinging: framework and a vertically positioned 'lianimrork hinn'edly attached to the frame of a closure. and adapted to normally rest.- agi'ainst said closure, means joining; both of said frameworl for positive united action, and a reversible lover arm detaehably attached to said framework and operable in a vertical plane with said closure, and positinned to slidably and operably engage said closure to outwardly extend said framework upon opening: the closure.

In a fly scar-er. a horizontally positioned swinging framework hinn'edly attached to the top frame of a closure. a vertically posiitioned frame work hine'edly attached to the side frame of said closure, means operably joining said frameworks for positive united action. means to adapt said framework to a right; or left hand opening closure, said means conntirisinn a sinnously formed lever arm detachably attached to said fran'imvork and operable in a vertical plane with said closure, and means attached to said closure to slidably engage said lever arm to out wardly extend said frame work upon openin; said closure.
